A Stainless Steel Double Ferrule Tube Fitting is a high-performance, precision-engineered fitting used to create a leak-tight, secure connection in instrumentation and process tubing systems — particularly in high-pressure, high-temperature, and corrosive environments.

🔧 What It Is:

Double ferrule tube fittings use two ferrules — a front and a back ferrule — to seal and grip the tube:

  1. Front Ferrule: Creates a leak-tight seal on the tubing and fitting body.

  2. Back Ferrule: Provides tube grip by swaging (compressing) onto the tubing.

They are widely used in critical applications where leak-free performance is essential.

📐 Key Features:
PropertySpecification
Material Stainless Steel 316 (standard), sometimes 304
Tube Sizes 1/16" to 2" (imperial), 2 mm to 50 mm (metric)
Thread Connections NPT, BSPT, BSPP, ISO, or SAE male/female threads
Pressure Rating Up to 3,000 PSI (depends on size, wall thickness, and manufacturer)
Temperature Rating Up to 1200°F (648°C) with SS316
Standard Brands Swagelok®, Parker A-LOK®, kalpataru
Advantages:
  • Leak-free seal under high pressure and vibration

  • Easy installation — no welding or soldering required

  • High reliability — ideal for critical instrumentation lines

  • Reusable and remakable without losing integrity

  • Excellent corrosion resistance, especially with SS316

  • Vibration-resistant due to secure tube grip

🧰 Applications:
  • Instrumentation and control systems

  • Oil & gas (offshore and onshore)

  • Chemical and petrochemical processing

  • Power plants and nuclear systems

  • Analytical and laboratory equipment

  • Hydrogen, oxygen, and high-purity gas lines

Twin Ferrule Fittings - Tube Union

Twin ferrule fittings are a type of compression fitting widely used to connect tubes in various industries like instrumentation, hydraulics, and process piping. The design typically consists of two ferrules—a front ferrule and a back ferrule—that create a strong, leak-tight seal on the tube when tightened.

What is a Tube Union in Twin Ferrule Fittings?
  • Tube Union is a fitting used to join two lengths of tube together in a straight line.

  • It typically consists of two threaded ends where tubes are inserted and compressed using twin ferrules.

  • The union provides a removable connection that can be disassembled without cutting the tube.

Key Features:
  • Leak-proof: The twin ferrule design ensures a secure, metal-to-metal seal.

  • Reusable: Can be taken apart and reused multiple times without loss of sealing performance.

  • Material: Commonly made of stainless steel, brass, or other corrosion-resistant metals.

  • Applications: Used in high-pressure systems, chemical, pharmaceutical, and instrumentation setups.

Stainless Steel Parallel Male Stud Connector

A parallel male stud connector is a pneumatic or hydraulic fitting used to connect a male-threaded tube or pipe to a female-threaded port. It typically features parallel threads (as opposed to tapered) for precise mechanical connection, often used in instrumentation, process, or pneumatic systems. Made from stainless steel, it offers high corrosion resistance and durability.

Typical Technical Specifications
ParameterTypical Value
Material SS 304 / SS 316 Stainless Steel
Type Parallel Male Stud Connector
Thread Type Parallel threads (BSPP, NPSM, or ISO parallel threads)
Size Range 1/8″ – 1″ nominal diameter
Pressure Rating Up to ~6000 psi (depending on size and system design)
Temperature Range –20 °C to +200 °C
Seal Metal-to-metal contact or optional PTFE seal for leak-proof connection
Standards ASTM A182 / A276 (material), ISO 228 / ISO 7-1 for threads
Finish Smooth, corrosion-resistant stainless steel
Applications Instrumentation panels, pneumatic systems, hydraulic lines, process piping, chemical plants
Key Features
  • Parallel Threads: Ensures precise fitting without thread taper; typically sealed with an O-ring or PTFE tape if required.
